T aZZ whom it may concern:

Be it known that I, J OHN WILLIAM RYAN, a subject of the King of GreatBritain, and resident of Gledhow Mount, Harehills Lane,

' Leeds, in the county of York, England, have invented a certain new anduseful Improvement in Fallers or Gill Bars for Treating TextileSubstances, of which the following description, having reference to theaccom- W panying sheet of drawings, is a specification.

In the type of machine to which this invention relates the fallers orbars which carry the pins for combing or treating the M fibroussubstances have to be raised from being operated by their pairs ofscrews in one plane so that they may be operated in a contrary directionby screws mounted in a higher plane. In these operations each 959 falleris raised by cam action from engagement with its lower operating screwsinto engagement with its upper operating screws and on being thus raisedwhen the upper screws are engaged with, a slight advancing movement isgiven to each faller prior to the time that it reaches its highestposition, thus provision has to be made to permit this slightlyadvancing movement prior to the faller reaching the upper surface of itsguiding bars as is well understood. Heretofore this provision has beenmade by the outer guiding ends of the horizontal slides or guides forsaid fallers being of an inclined character thus the lower edges ofthese inclined guiding surfaces have had to be limited in width ordimensions so that the whole of the abrading actions of all the fallersmoving over said surfaces was to be withstood by the comparatively smallguiding surfaces of said bars, hence considerable deterioration and wearhave been experienced in connection with these guiding surfaces. Toobviate these disadvantages and defects by constructing said end guidingsurfaces on the bars of the formation hereinafter described and by theformation of the fallers as is hereinafter explained, is the object ofmy present invention. This object I attain by following the method ofconstruction or formation hereinafter described and illustrated by theaccompanyin sheet of drawings wherein i ig. 1 is a sectional sideelevation of the upper and lower screws of a gill box or gill frame onone side of said frame, a pair of screws ofthe samecharacter, aremounted on the opposite side of the frame in manner well known. Only oneguiding bar and the fallers in connection therewith are shown in thisfigure. w l l v i 1 ,Fig. 2 is a view of the parts shown by Flg. 1looking in the direction from left to right of said figure- Fig. 3 is aplan of certain of the parts shown by Fig. 1..

Fig. 4 is a perspective view of the end part of a faller constructed inaccordance with my invention.

The well known upper screw A and lower screw B form the pair of screwson each of the machines.

To attain the object of my invention instead of forming the outerguiding ends a of the horizontal slides or guides 2 of the inclinedcharacter as heretofore, I now form them straight and to meet thisaltered formation I now make the inner surfaces 6 of the guiding groovesc in each of the fallers 3 of an inclined character, that is to say,said inner surface from the point to to the upper edge 4.0 is straightwhile the lower half from the point w to the lower edge w is inclined sothat said groove gradually increases in depth from the point to to thelower edge 10 By this formation of the guiding surfaces 1), when thefaller 3 is ascending from the position shown in Figs. 1 and 2 it willmove half of its vertical path with its straight surface between w, 'win engagement with the outer end a of the guiding bar 2 wherefore thispart of its path will be perfectly upright. After travelling throughthis half of its vertical path, the outer inclined end 3 of the faller 3will be in contact with the surface at of the screws a and so willcommence (under the pressure of said surface of) to move. from right toleft. The moving in this horizontal direction of each faller 8 ispermitted by the inclined portions of the surfaces 5 from the point w tothe lower edge ta to come into. contact with the end guiding surfaces orof the bars 2 so that as the screws A gradually move said fallers 3forward, the inclined portion between w and w of the faller permits thishorizontal movement because the advancing of the surfaces cl on thescrews a correspond and agree with the inclination of the surface 6between the points and 'w As is well known the lifting or raising of thefallers 3 from the lower positions shown by Figs. 1 and 2 into thehigher position as shown by the faller 3 is effected or carried out'bythe rotary cam 4, which acts u on the lower edge of the'faller as isshown y said Figs. 1 and 2. I

By making use of the arrangement and construction of the guides 2 withtheir outer guiding ends a of the formation described I have found thatsaid guiding ends a wear evenly whenever such occurs so that they are atall times perfectly straight, and such wear is not; so apparent uponsaid surfaces at as it is when the inclined formation has to bemaintained, because as these ends wear so also do all the guidingsurfaces 1) of the fallers, wear and the sum of the wear of the fallersis represented by the wear in the multiplicity of the surfaces 6.

Such being the nature and object of my said invention what I claim is 1.A gill or faller bar having each of the bases of its guiding roovesformed with a straight part parallel to the two side surfaces of saidgill or bar and the remainder of said base surface at an angle to thesaid parallel part.

2. A gill orfaller bar having each of the bases of its guiding grooveswith a part parallel to the outer side surfaces of said bar and theremaining part of said base at an angle to the other part in combinationwith a guiding bar having its and guiding surfaces substantially atright angles to its longitudinal uidin surface.
